Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more

P2P as a New Spam Medium, Moving From PoC to Full Operations

Spam on P2P networks used to be mainly with advertising inside downloaded movies and pictures (mainly pornographic in nature), as well as by hiding viruses and other malware in downloaded warez and most any other file type (from zip archives to movie files). Further, P2P networks were in the past used for harvesting by spammers. Today, P2P has become a direct to customer spamvertizing medium. This has been an ongoing change for a while. As we speak, it is moving from a proof of concept trial to a full spread of spam, day in, day out... more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

OpenDNS Adopts Proposed DNS Security Solution: DNSCurve

For more than 15 years, the IETF has been working on DNSSEC, a set of extensions to apply digital signatures to DNS. Millions of dollars in government grants and several reboots from scratch later, DNSSEC is just starting to see real world testing. And that testing is minimal -- only about 400 of the more than 85,000,000 .com domains support DNSSEC, fewer than 20% of US government agencies met their mandated December 31, 2009 deadline for DNSSEC deployment, and only two of the thirteen root zone name servers is testing with even dummy DNSSEC data. more

RIPE NCC Publishes Case Study of youtube.com Hijack

The RIPE NCC conducted an analysis into how this incident was seen and tracked by the RIPE NCC's Routing Information Service (RIS) and has published a case study... more

Nitol and 3322.org Takedown by Microsoft

Reading this morning's blog from Microsoft about "Operation b70" left me wondering a lot of things. Most analysts within the botnet field are more than familiar with 3322.org - a free dynamic DNS provider based in China known to be unresponsive to abuse notifications and a popular home to domain names used extensively for malicious purposes - and its links to several botnets around the world. more

Clarke and Knake’s “Cyberwar”

I just finished reading Richard Clarke and Robert Knake's book Cyberwar. Though the book has flaws, some of them serious, the authors make some important points. They deserve to be taken seriously. I should note that I disagree with some of my friends about whether or not "cyberwar" is a real concept. Earlier, I speculated that perhaps it might be a useful way to conduct disinformation operations, but it need not be so limited. more
